Raven Bramblebutt and the Feral Children: Raven Bramblebutt, Book 1

Ten-year-old Sevilla Ray has a secret: whenever she gets really scared by some larger-than-life menace, such as a not-so-dead Ghost Moth or the Angry Woman of Kits Beach, she shrinks to 18 inches tall. When one day she shrinks and rides off on her Irish Setter, Raven, her life will never be the same. It’s bad enough that her friends think she is involved in black magic, but she is not the only one with magic. The unthinkable has happened: Her magic has followed her back to her safe mountain town.
